If you want a detailed security rating about your ycomp5_3_19_0.dll (and all other running background processes) download the free trial version of Security Task Manager.

Note: Any malware can be named anything - so you should check where the files of the running processes are located on your disk.

Check it out!

An enhanced process viewer, that displays all the standard information as well as a unique security risk rating based on analysis of hidden functions (keylogging, stealth, browser surveillance, autorun entry,...)
